Etymology: Glanidium: Diminutive of Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); botocudo: Name is in reference to the Botocudo, the generic name given to native indigenous people wearing artifacts ('botoques') on ears and lips. Those Indians were the original inhabitants of large extensions of the Floresta Atlântica (Paraíso, 1992), including the lands along the rio Mucuri valley and far west, to the rio Doce, range of the new Glanidium species. A noun in apposition.

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 2; Rückenflossenweichstrahlen (insgesamt) : 5; Afterflossenweichstrahlen: 11; Wirbelzahl: 36 - 37. This species is diagnosed from other species of Glanidium, except G. albescens, by the presence of small dark spots over a pale yellow ground color (vs. large dark blotches over a pale brown ground color). It differs from G. albescens by having pectoral fin spine length, about 21-26 % in SL (vs. 17-20% in SL), 10 ribs (vs. 9) and 36-37 vertebrae (vs. 38-39). The possession of 36 or 37 vertebrae separates this species from G. cesarpintoi, G. albescens, G. leopardum, G. melanopterum, G. catharinensis, and G. ribeiroi (with 38 or 39 in G. cesarpintoi, 38 or 39 in G. albescens, 40 or 41 in G. leopardum, 41 in G. melanopterum, 41 in G. catharinensis, and 44 in G. ribeiroi). It also differs from other species by having anterior margin of the pectoral-fin spine with serrae on its entire margin (vs. serrae restricted to distal portion of spine in G. melanopterum, G. catharinensis and G. ribeiroi or smooth anterior margin in G. leopardum) and by a long sharpened ventral process on urohyal (vs distinctly short robust process in G. melanopterum, G. cesarpintoi, G. catharinensis, and G. ribeiroi) (Ref. 93811).
Occurs in lotic sections of rivers and also lakes. Active at night. Feeds on allochthonous resources, such as beetles, and autochthonous aquatic invertebrates, such as insect larvae
and gastropods based on gut contents of 8.2 cm SL specimen (Ref. 93811).
